A waterboilers; andv consists in the provision y onev of theobjects of-the Be it known .thatl I, HowARD A, SMOCK, ay citizen ofthe UnitedStates, residing at Indianapolis, inthe county'of Marion and State vofIndiana, have invented certain new and useful Improvements Vin Methodsof Manufacturing Steam and Hot-lVater Boil` ers, of which the followingis asp'eCiiCation.

This invention relates to a method of constructing andmanu'facturingfsteam and hot of a method'f boiler construction which issimple, eicient andpecono'mical.

The rapid increase'in the use, among 'automobile;l manufacturers, ofanfoutfit comprising a boiler` for simultaneously heating sev-Veralliquid solutions in different tanks for the removal of grease, dirt,enamel and paint from automobile; parts, has created a lar e, demand fora"sinall, `compact and portab e Y outfit consisting of va boiler' and anumber of yassociated' or connected tanks, and: it [is present inventionto supply suchV demand. i j V The method of assembling and arrangingYthe various parts of my improved construction,` is described V`in the,:following specification and illustrated in vthe accom-1 drawings,forming a' part hereof, in whic v V,Figure l illustratesthe irs'tfstepin the assembling of'rmy improved boiler.- Fig. 2

illustrates the second step in lthev assembling of the boiler. Fig. 3 isa horizontal 'sectional view of a-j complete assembled, boilerconstructed in accordance with my invention, on the* line 3- -3 in`Fig.i 4, Fig. 4 is a `central vertical sectional View of an assembledboiler and-associated tanks, on the line 4-4 in Fig. 3.` Fig. 5 isafragmentary detail perspective view,'onan enlarged scale, showing moreclearly the method of joining the ends of the cylinders together. v Fig.6 is' a fragmentary cross sectional view, on 'an enlarged scale, showinga permanent joint for securing the meeting v edges of each Vindividualcylinder together.

Referring to the drawings, the complete boiler comprises a pluralityofconcentrically varranged cylinders 10, 11, 12 and 13. Each of thesecylinders is formed out of a flat metal sheet, and when the operation ofrolling a sheet is completed the meeting edges of the sheet are heldtogether in a temporary manner by means of a metal cleat 14 whichoverlaps the meetingedges, the cleat'being Specification of LettersPatent;

The completed boiler arranged uponA a base 25 ot aboiler setting` havingalso arranged therein the usual grate-bars 26.v The boiler isalsoenclosed by a casing or shell with/afflue-opening 28 through whichthe burnt products of combustion escape to the chimney. Y l, f Y e 'Asshown in Fig. 3 a plurality of tanks,

form the outer section of f which l designate A., B and C, are arrangedaround the boiler, and each oithesentanhs communicates with one oi theVcompartments 22byy means of the conductor pipes 3() and 31,whereby a'circulation oit the liquidin each tank and its connected compartment 22is'established independentlyoi th-at in the other tank, when the liquidsare heated in the boiler. 1
